So because I got sort of scammed by virwox I had to buy 0,044 BTC in order to withdraw my money fro there. So i downloaded bitcoin core and clicked on request pay and put the receiving code in virwox to get my payment. Not knowing anything about bitcoins I asked support for help on why I didn't receive my bitcoins.The operator linked me to a page on
https://blockchain.info and said that probably my client has not yet read the whole block chain yet. I checked bitcoin core and it doesn't say anything about "reading the block chain". But in the bottom of the client something like syncing with the net (1 year and 33 weeks), is it going to take that long?? Please help, I don't want to lose my money)
If you don't want to lose money, it might be a good idea in the future to learn a little bit about what you are trying to do BEFORE you do it.
There are many different bitcoin wallets available.
Some, like Multibit and Electrum, are "lightweight" wallets. They use SPV (Simplified Payment Verification) to keep track of the bitcoins that you've received. These wallets are able to get up and running very quickly since they don't need to store the entire blockchain.
Others, like Bitcoin Core and Armory, are "full nodes". These are fully participating peers on the peer-to-peer bitcoin network. They store and validate the entire transaction history of EVERY single bitcoin transaction that has ever occurred since the beginning of bitcoin in 2009.
Since you didn't bother learning about the wallets first, you chose to run a "full node". Thank you, the network appreciates your willingness to dedicate 33 GB of disk space to store the transaction history, and your willingness to dedicate some of your computer's processing power to enforce all the consensus rules while relaying transactions and confirmation blocks.
In order to act as a "full node", your wallet will first need to synchronize ALL the past transactions that have occurred. The "1 years and 33 weeks" isn't how long it will take, but rather how long ago you are caught up through in your synchronization. Depending on the processing power of your computer, it will take anywhere from a few hours to a week for your computer to get fully caught up with synchronization. Once it is caught up, you will see your bitcoins in your wallet.
In the meantime, you should probably create a backup of your wallet. That way if your computer dies, or you accidentally delete your wallet, you'll be able to recover and still be able to access your bitcoins.
